Describe the bug

When adding a Shell-Descriptor to the AssetAdministrationShellRegistry API's shell-descriptors endpoint, that should raise a conflict. That's currently not the case, the shell-descriptor is overwritten.

To reproduce

1. POST /shell-descriptors with payload

   }

2. Execute the exact same request but replace the idShort with "idShort": "overwritten".

Expected Behaviour

I'm expecting a conflict here but I simply get the permission to overwrite the data that's already there. 409 Conflict is the specified behavior in the normative openapi files [1].
